My breast have been sore all month and ive been experiencing some cramping as well. no bleeding of any sort .i also get a watery mouth as well ?

Go get a test: ...first with these constellation of symptoms, test for pregnancy. You can do at anytime but if you have not missed your period, do a first morning urine.

Pregnant?: any chance you are pregnant? Would be high on list of possible causes. Recommend home pregnancy test on first morning urine. If neg repeat in 7-10 days. If both neg unlikely you are pregnant. Breast soreness and uterine cramping suggests hormonal cause. See you doctor for evaluation. Hope this was helpful. Best of luck.
